I have an A'Pexi World Sport exhaust, and before, I did not plan on getting an intake. However, today my friend told me that rather having just an intake, having an intake with my exhaust would be worth it. He said I would be able to gain at least 5-10 horsepower. Is that true? I was always against buying an intake because a lot of people say it is useless, even with AEM's. I dunno, what do you guys think?

I was planning on getting headers next, but now this whole intake thing came up, and I'm just wondering now...Should I stick with the headers or get an intake? Which would give me more hp gain without losing low-end power and torque? I already have an exhaust, so which combo would be best?
